For those who try to pull from Persona Gacha, this is my advice, DO NOT EMPTY OUT YOUR STARS IN THE FIRST DAY. The gacha is last for 10 days if i'm not mistaken, BE PATIENT. That regret is going to haunt you. If you saved a lot of stars, try to scout once a day (either single or 10x pull). Everyone's luck differ from person to person. In my experience, scout in 3rd day above until the last hours often bring more hope (again, everyone luck is different). When i get Himari QT in JP version, i scouted in the 4th/5th day.

May luck be with you, happy playing!
